Okay, here is the update:
After approx two hours on the phone with my internet provider (Brighthouse Cable)....
First the Customer Service Rep ran through all the basic diagnostics. Cleared the cache, had me go to c promt mode and pinged the site by name and numerical, had me disable the firewall and try again. Also had me go to c prompt and do a ipconfig/flushDNS. (I don't know what that means, but I took notes!!)
When that didn't work she transferred me to her 'mentor' (her words, I thought that was cute). We used to use Supervisor in my day (even though it was just the person in the cubicle next to us!), but Mentor makes them sound so much more knowledgeable and less hierarchical. I would have been more impressed by that except that....
Her mentor couldn't help me much either. He did the ping and it failed rather quickly, just like the other times. I couldn't understand why it would fail in c> mode so fast, when through the browser would keep waiting and not show an error/fail message. He also tried to load the site and couldn't. He was very certain that Brighthouse has not blocked the site!!! I asked him specifically, because "I would hate to have to change providers for that reason"!!
He believes that the issue lies in the 'host of site not updated on DNS server of my provider site' (not quotes, from my notes, so I hope it makes sense). He explained to me how servers update and sometimes change addresses regularly and also go trough 'relay' sites, and possibly the host site/relay site has not yet updated to my providers current information. I hope that my notes/translation makes sense to someone, anyone?
Unfortunately, I am not very knowledgeable in this technological realm and could not even ask the proper questions. I felt like a two year old asking "why" "why", "why doesn't it work?". If anyone knows of any specific questions I should ask, please let me know.
So here I am, still SOTTless, with no true knowledge of what is going on in the world!! Kinda Caveman-ish!! But I have been able to catch up on some forum posts and check out the latest video 'Q&A with Laura', which is exceptional! So all is good and maybe the Universe is guiding me to the places where my attention should be at the moment?!
